Interesting. Both boards are identical as far as I can tell, both have the
connectors, no sign of a "Data" board, and no 2708's in sight.

What do you plug into the "Temp Interface"? I'm guessing the A/D circuitry
would be part of the temperature probes, which I didn't get :^(

Guess for the time being at least I can leave these out and have a couple
more free slots.
